ASU Law Professor Gary Marchant gave two presentations at the annual meeting of the Society for Risk Analysis (SRA) in Denver on Dec. 8 and 9. Marchant’s first presentation, entitled “Nanotechnology: From Harmful to Helpful?,” examined the possible role of hormesis in the toxicology of nanomaterials, and the risk management implications of any such connection. His second presentation, “Genetic Biomarkers of Risk in Toxic Tort Litigation,” co-presented with CLSI advisory board member Kirk T. Hartley, reported on recent developments in using genetic biomarkers in benzene and asbestos toxic tort cases. Both presentations are available, below. At the meeting, Marchant was also elected Chair of the Risk, Policy & Law Specialty Group of the SRA for 2015.
